How can I do the private networking for the boot2docker docker container ?
For example, If I have a webapp, I can do the following in Vagrantfile
myapp1.vm.network "private_network", ip: "1.2.3.4"
myapp2.vm.network "private_network", ip: "1.2.3.5"
myapp3.vm.network "private_network", ip: "1.2.3.6"
Then I can use my browser to access my webapp at
http://1.2.3.4
http://1.2.3.5
http://1.2.3.6
How can I achieve the same result in docker easily ?
I also looked at How to expose docker container's ip and port to outside docker host without port mapping?
But in my boot2docker1.3, it said the interface eth0:1 does not exist
I looked at https://docs.docker.com/articles/networking
The tutorial does not work for boot2docker in mac.
Any help would be appreciated, thankyou!
I believe the instructions here, linked from this question give what you are looking for. The key is this line:
sudo route -n add 172.17.0.0/16 172.16.0.11
which tells your Mac how to route to the private network inside the VirtualBox VM that the Docker containers are on. (Obviously the specific addresses can change for your specific situation)
This still doesn't give you the ability to assign specific IP addresses to specific containers; as I said an add-on like weave can do that. (note: I work on weave)
You may also like this article which gives a beginner's overview of how Boot2Docker runs and illustrates how you have IP addresses inside the VirtualBox VM, and also an IP address of that box as a whole.
